Problems solved by technology

The existing polyester-cotton warp and weft yarn-wrapped polyolefin elastic fiber fabric dyeing and finishing process, due to the unreasonable selection of treatment liquid raw materials, process parameters, and process flow, causes the strength of the fabric to decrease, the elasticity to decrease, and the width to be unstable. And other issues

Embodiment 1

[0024] In the polyester-cotton warp and weft yarn-wrapped polyolefin elastic fiber fabric, the polyolefin elastic fiber is DOW XLA polyolefin elastic fiber, produced by Dow Chemical Company, the thickness of the fiber is 40D (Denier, Denire), and the tissue specification: polyester cotton CVC40+40D(XLA)X40+40D(XLA) 96X72 79".

[0025] The dyeing and finishing process adopted has the following steps in sequence,

[0026] a. Turn over the seam, the front and back are the same, the seam head is straight and firm, the edges on both sides are dense, and the stitch density is 28 stitches / 10cm;

[0027] b, Narrowing, first rolling material, the components of the rolling material are: 301L refining enzyme 10g / L, oxalic acid 1g / L, penetrant CWA 3g / L, the rest is water, the temperature of the rolling material is 55°C, after rolling the material is Stack in the crawler box at 60°C for 35 minutes, then wash with 80°C hot water in a 5-grid washing tank, and the width shrinks by 18%;

Abstract

The invention provides a dyeing and finishing technology for using polyester cotton warp and weft yarn to warp a polyolefin elastic fiber fabric, and belongs to a processing technology of an elastic fabric. The technology sequentially includes the following steps: turning and sewing of the cloth, shrinking, singeing, desizing, mercerizing, setting, dyeing, after finishing and pre-shrinkage. The dyeing and finishing technology decreases the density of the warp and weft direction during the preliminary treatment before the dyeing of the fabric, and leads the cloth easier to retract, and the width is sufficiently shrunk after the shrinkage, desizing and mercerization process, thus obtaining the cloth has good elastic effect and soft feeling. Compared with the prior art, the fabric has good tensile recovery property, stable and lower washing shrinkage and high temperature resistance, strong acid resistance and strong alkaline resistance, which is favorable for various professional finishing; therefore, the soft dacron-cotton warp and weft elastic fabric with high elasticity, good air permeability and strong moisture absorption property can be obtained.

Description

technical field [0001] The invention relates to a processing technology of an elastic fabric, in particular to a pre-treatment and post-finishing process of a polyester-cotton warp and weft yarn-wrapped polyolefin elastic fiber fabric. Background technique [0002] At present, elastic fabrics on the market are generally made of spandex, nylon and polyester interwoven. This kind of fabric is easy to shrink and melt when heated (high temperature), making it difficult to burn singeing. It is difficult to ensure the width, elastic elongation and rebound of the finished product when shaping. rate and weft shrinkage, and will be attacked by alkali and available chlorine, which will cause the elastic fibers to break bonds and hydrolyze, resulting in a decrease in elasticity and strength. And it is not resistant to high temperature finishing, such as anti-wrinkle finishing, waterproof and oil-proof finishing, and has poor dimensional stability. However, DOWXLA polyolefin elastic fi...
